Japan’s ‘Increasingly Severe’ Security Environment

Japan’s security environment is “increasingly severe”, according to the Ministry of Defense released its annual defense policy white paper. The report singles out China, Russia and North Korea as potential security threats involving cyber attacks, provocations on the high seas and nuclear weapons.

The paper also outlines further details regarding Japan’s new “dynamic defense”, a series of organizational reforms as well as a five-year procurement plan for defense equipment. The changes to the structure of the Japanese Self Defense Forces (JSDF) are the most sweeping since the end of the Cold War. The reorganization seeks to implement new capabilities while preserving old ones, without an increase in overall Self Defense Force manpower.

The crux of Japan’s new defense policy is the revamping of the three Self Defense Forces, Ground, Air and Maritime into a new joint “dynamic defense force”. The force would be highly mobile, capable of operating throughout the Japanese archipelago, especially on the outer fringes such as the Senkaku Islands where basing military forces is difficult. Taking a cue from the United States military, the Self Defense Forces would become more “joint”in nature, with two or more of the services capable of working in the field together.

Primary missions envisioned for the “dynamic defense force”include defending against invasion of remote islands, defending against cyber-attacks, containing an attack by special forces or guerrillas, disaster relief and noncombatant emergency evacuations. An NEO operation could be anything from rescuing Japanese nationals from terrorists to evacuating civilians from South Korea in the event of a war.

The defense budget itself will see a slight increase. The 2014 budget will be approximately $46.9 billion at current exchange rates — a 2.2 percent increase over 2013. This includes $1.88 billion in host nation support for U.S. forces in Japan.

Naval Forces

In response to China’s continuing naval buildup the Maritime Self Defense Force is also set to grow substantially. Twenty three new P-1 long-range maritime patrol aircraft will replace existing P-3C Orion aircraft.

The number of destroyers will increase from 48 to 54, adding 52,000 tons of ships. The two Aegis destroyers of the Atago class will receive BMD software upgrades, and two more Atago destroyers with be built, providing Japan with an overall BMD-capable destroyer force of 8. All will be equipped with the SM-3 Block IIA interceptor. As announced in 2010, the submarine force is set to increase from 16 to 22. The number of destroyer escort squadrons will increase to 14, while the number of submarine squadrons will increase to six.

One interesting development is the mention of a new destroyer type with modular capabilities similar to the Littoral Combat Ship. The new destroyer is projected to be smaller, with a towed sonar array instead of a sonar in the bow. It will be capable of being fitted with modular minesweeping equipment. The fielding of this new destroyer and an overall increase in the destroyer force will coincide with a 25% reduction in the number of minesweepers, set to drop to 18. The MSDF is apparently trying to increase the number of destroyers while not increasing overall manpower and maintaining a strong minesweeping capability.

Air Forces

The Air Self Defense Force will likewise see a number of changes. In order to guard against Chinese airspace violations over the Senkakus and Ryukyus, the ASDF will double the number of F-15Js based at Naha Air Base on the island of Okinawa. The SDF will also double the number of Airborne Early Warning Squadrons controlling Japanese E-767 AWACs and E-2 AEW aircraft from one to two, with one squadron, the 603rd, permanently based at Naha. Four more AWACs or AEW aircraft will be purchased.

The ASDF fighter force is planning to expand. A new fighter squadron will be established while the ASDF’s only reconnaissance squadron will be disbanded. Twenty-six F-15J fighters will receive upgrades. Japan is placing a down payment on its first batch of 28 F-35A Joint Strike Fighters (JSF), which will be based at Misawa Air Base.

Japan will also acquire several high-end unmanned aerial vehicles (UAVs). The Endurance Unmanned Aerial Vehicle program will almost certainly be filled by a purchase of three Northrop Grumman Global Hawk UAVs. The UAVs will be jointly operated by the three services.

Ground Forces

Japan’s land-based air defense network will also receive an upgrade. All six Patriot-equipped air defense artillery groups will be equipped with the new, longer range Patriot PAC-3 Missile Segment Enhancement, giving them increased ability to conduct point defense against North Korean and Chinese ballistic missiles.

The Ground Self-Defense Forces will adapt to become more strategically agile. Japan is currently building up an amphibious brigade around the Western Army Infantry Regiment. The new brigade, to be based at Nagasaki, will be responsible for defending the Ryukyu and Senkaku islands. The brigade will be composed of several regiments (battalions) totalling 3,000 troops in all and equipped with 52 Amphibious Assault Vehicles. Seventeen V-22 Osprey tilt rotor aircraft will provide lift for a quick reaction force.

A restructuring of the GSDF will turn half of standing units into so-called “rapid deployment formations”, brigades and divisions capable of rapid movement to respond to domestic crises (such as earthquakes and other natural disasters) and capable of reinforcing Japan’s periphery. The rapid deployment force will consist of three divisions and seven brigades. Towards that end, Japan is shedding most of its tanks, retaining a core force of about 300. Mobile firepower will be provided by the new Mobile Combat Vehicle, a wheeled fire support vehicle analogous to the Italian Centauro.

Finally, citing increased Chinese activity in the East China Sea, the GSDF will station coastal observation and area security units throughout the Ryukyu Islands, to provide a security presence and monitor Chinese military movements in the area. Mobile air defense radars will be deployed to remote islands. Japan will also be standing up nine new anti-ship missile companies, which if moved to the Ryukyus could close the Miyako Strait to foreign ship traffic.

Cyber

According to the white paper, Japan is establishing a Cyber Defense Group, to be placed under the C4 Systems Command. Reflecting the growing importance of cyberwarfare, organizationally the CDG will be only two levels under the Minister of Defense. The unit will monitor the Ministry of Defense and SDF networks 24 hours a day to prevent “increasingly sophisticated and complex”cyberattacks. The CDG will also interface with each Self Defense’s individual cyberwarfare unit.

Curiously, the document says very little about a cornerstone of Prime Minister Shinzo Abe’s defense reform: collective self defense, specifically with regards to the United States. The paper was likely written before the policy became official earlier this summer.

The Japanese are realistic and they know who are their friends and adversaries. Their Defence Forces are continuously being upgraded for possible conflicts. Japan can be expected to have nuclear capabilities in due course, as the nations in the region who have them, continue to pose serious threats to its survival.

Japan already has Nuclear Capability. They probably don’t have as much Nuclear Weapons as Israel does, but, they probably do have at least 100 Nuclear Weapons. It’s not widely known, to most of the world. But Japan, is actually the 2nd Nation in the World to Design, Develop and Explode an Atomic Bomb, under the F-Go Project, in or around, 12 August 1945 CE. Just a few days after the United States exploded theirs. They exploded their first Atomic Bomb. Unlike the American testing of the Atomic Bomb, the Japan Atomic Bomb test killed approximately 70,000 people, in Konan (now called Nungnam, North Korea). They built 2 Atomic Bombs, the second bomb was later dismantled and destroyed. Because first, they had noway to deliver it, apparently all their I-400 Submarines were all out fitting the war. and secondly, they thought if the United States had found out about the second bomb. Mainland Japan would have been reduced to a parking lot and all the United States had to do after that, is send in the Marines and paint out the parking slots.

It’s been long said that if you ever want see Asia in general, and the Korean Peninsula in particular, united, just have any one country there declare war on Japan! The Japanese have nobody to blame but themselves for how their neighbors view them. While the present-day Japanese didn’t have anything to do with the atrocities committed by the ‘leadership’ of WWII and the immediate years prior to that, those modern-day types have been flat-out disingenuous about the legacy and consequences of their country’s actions in that time period.

One should not confuse bushido with nazism , one has been around a 1000 years. The other lasted 12. Years , japan has breeder reactors , plenty of plutonium . They could build a nuke in a week . If they have not already . I can here the moan as Nippon sup passed the Arizona memorial. What Fools we Americans are.

Japan already has Nuclear Weapons Technology! Back in World War II, the Imperial Japanese Empire, under Ni-Go Project and F-Go Project. Created two Atomic Bombs, and exploded one, and dismantled the other to prevent Soviet capture. The tests were conducted in what is now North Korea. The first of two bombs tested killed ~70,000 Koreans.
